US 7,073,424 B2 · Method and plant for the destruction of a fuze mounted on a munition

Abstract

The invention concerns the field of ammunitions equipped with their fuze, found on the battlefield. Such ammunitions represent a major pyrotechnic risk. The problem consists in destroying the fuze so as to be able to dismantle said ammunition. The method consists in placing said ammunition (1) in a closed chamber (5) to carry out at least once the following cycle: depressurizing the chamber (5), dissolving the fuze (2) of the ammunition (1) with a liquid corrosive agent, drawing off the gaseous effluents towards an auxiliary chamber (7), reopening the chamber (5) after dissolving the fuze (2), removing the ammunition (1), recovering the mixture resulting from the attack of the fuze (2) by the liquid corrosive agent (6) and treating it by pyrolysis.

Dependent claims

A method for destroying fuzes mounted in munitions, each munition comprising a body and an explosive dispersion charge initiated by a fuze, with at least one munition in a closed chamber, wherein the following cycle of operations is carried out at least once:

a reduced pressure is created in the chamber;
only the fuze of the munition is dissolved by a corrosive liquid agent;
gaseous effluents are withdrawn to an auxiliary chamber for subsequent treatment;
after the fuze has been dissolved, the chamber is reopened;
the munition is removed and packaged for subsequent treatment;
and
another destruction cycle is capable of being carried out until the corrosive liquid agent is no longer sufficiently corrosive to provide an additional cycle.
